IJZQUID-DISPENSING UNIT.

Application filed July 18,

This invention relates to apparatus for dispensing gasoline or other liquids and it has to do more especially with improvements which adapt the apparatus to installation in masonry structures.

In connection with gasoline stations at 1s becoming quite common to employ cornpressed air for feeding gasoline to the dispensing hose, and to use meters for measuring thegasoline so fed, thus doing away wlth measuring pumps, and this innovation permits the measuring and dispens ng un ts or apparatus to be built into the walls or plllars of the station or in masonry piers constructed especially for the purpose.

Important objects of the invention are to provide a construction that Wlll expedite building of the units; that will greatly facilitate and cheapen their installation; that will permit of ready inspection and repair; that is very compact, and wherein all connections, etc. are accessible from the front, thus eliminating the hitherto necessity of provldm accommodations for getting at the units rom the rear, which proved especially undesirable and inconvenient when the units were built into the walls of the station and, when placed in masonry piers,-required excessively large, hollow structures so as to allow the workmen to get inside the piers while installing the units, executing the necessary pipe and electrical connections, inspecting the apparatus, or making repairs.

Another object is to efiectively seal the partsv of the cabinet containing electrical wires and connections from the compartment housing the gasoline line connections and wherein vapors are liable to accumulate, thus avoiding the possibility of fires being started by electric sparks.

A further object is to provide means for locking the hose nozzle inside the cabinet, as at night when the attendant is ofi duty, thus doing awa with the necessity of removing the hose w en the station is unattended.

The foregoing objects, with others hereinafter appearing, are attained in the embodiment of the invention illustrated in the accompanying drawings wherein Fig. 1 is a front elevation of my improved dispensing unit mounted within a masonry pier; Fig. 2 is a horizontal section on the line 22 of Fig. '1; Fig. 3 is a substantially central vertical section through the apparatus; Fig. 4 is a 1927. Serial No. 206,505.

rear view of the front plate with the apparatus assembled thereon; and Fig. 5 is a sectional detail on the line 55 of Fig. 1.

Adapted to be built into the masonry structure 1, which may be the wall or the pillar of a station, or a pier constructed especially for the accommodation of the apparatus, and which may be of brick, cement, or other building material, is a cabinet 2 of relatively heavy sheet metal,'to the front,

open side of which is riveted, welded or otherwise secured, an angle iron frame 3. Adapted to be secured, as by screws or bolts 4, to the vertical flange of the frame 3 is a substantial metal plate 5 that is preferably formed of a casting. A relatively large rectangular' opening 6 occupies the lower portion of the plate 5, and above this opening is one designated 7 Fitted within this latter opening is a member 8, which is preferably a casting, and it is secured to the plate 5 by fas-- tening means 9 that are engaged through registering apertures in the plate and in a peripheral flange 10 of the member 8 which overlies the portion of the plate 5 surrounding the opening 7. The member 8 has secured to it, as by means of a strap 11, a meter that supports an electric light bulb 21 in a,

position to illuminate the dial of the meter, and said bulb is housed within and protected by a hood 22 that is fitted within the boss 19 and incorporates a wall 23 by which the receptacle 20 is sustained. Suitably connected, with a vapor-tight joint, to the rear end of the boss 19 is the forwardly projected upper end of a conduit 25 through which the electric wires 26 are led to'the receptacle 20 from an outlet box 27 that is located within the lower rear portion of the cabinet 2.

A liquid or gasoline line, designated generally by the reference numeral 30 and built up of standard parts, extends from a point within the lower portion of the cabinet alongthe quantity side and forwardly of the outlet box 27, to the lower portion of the meter 12 and therebeyond and upwardly'to a point where 1t is extended through an aperture in the upper left hand corner of the plate 5 (as the parts are viewed in Fig. 1). Connected, by means of a coupling 31 to the end of the line forwardly of the plate 5 is the dispensing hose 32. The line 30 involves the usual strainer 30 and a shut-off valve 33 whose Weighted operating lever 34 is normally held elevated, so as to maintain the valve open, by a fusible link 35. In case of fire the link melts and the lever drops by gravity to shut off the flow of gasoline to the hose.

The opening 6 is normally closed by a door that is connected by a hinge 41 to the plate 5 along one side of said opening, and the door is adapted to be secured in closed position by a lock 42 that cooperates with apertured lugs 43 and 45 that are preferably formed integral with the plate 6 and the door 40, respectively.

The hose 32 is equipped with the usual nozzle 45 involving a valve 46 with its actuating trigger 47. To dispense the liquid it is only necessary to operate the valve by means of said triggerand the gasoline will be fed by air pressure through the system, the meter indicating the quantity that is dispensed. Ordinarily the nozzle of the hose is hung outside the cabinet 2 as by engaging a part of the hose adjacent the nozzle over. a hose-hanger 49 that is supported at a convenient point with respect to the dispensing unit, as on the side of a pier in which the unit is housed, as indicated in Fig. 1.

Before leaving the station, as at night, the attendant unlocks and opens the door 40, and removes the nozzle end of the hose 32 from its usual hanger 49 and engages it over a hook 50 that is supported by the left hand wall of the cabinet 2 near its lower front corner. The adjacent corner of the door 40 is provided with a notch 51 for the accommodation of the hose 32 so that the door may be closed, while the nozzle is thus supported Within the cabinet, and locked to prevent unauthorized persons from gaining access to the nozzle of the dispensing hose.

In the manufacture of the units, the meter 12 with the liquid or gasoline line 30, the electrical conduit 25 and outlet box 27 With the wires enclosed and the receptacle 20 in place and connected to the wires, are assembled and mounted upon the plate 5. All of this may be done in the manufacturing plant and the parts tested to insure. the apparatus being in proper condition. The plate, with the aforesaid parts mounted thereon, and the cabinet are then shipped to the place of installation. Here the workmen mount the cabinet within the masonry structure'during the process of construction and the liquid or gasoline line 55 and the electrical conduit 56, which lead from the respective sources of gasoline supply and electric current, are entered through apertures provided for the purpose in the bottom Wall of the cabinet. After this is done, the front plate 5 is secured by the fastening means i to the frame 3 of the cabinet; the door 4-0 is opened and the electrical conduit 56 is connected to the outlet box 27 and the,

be built in single or multiple units. It is" used in multiple when intended for the dispensing of the regular and the high test grades of gasoline, and in such a case the plate 5 is made large enough to accommodate two meters with their appurtenances, as hereinbefore described, and two doors close the opening corresponding to the opening 6 in the single unit. This is such an obvious modification that specific illustration of it is deemed unnecessary.

It may also be explained that the units may be mounted on opposite sides or on all four sides of a pier or column, and because of the compactness of each unit, said piers or columns may be ofrelatively small cross section.
